During an hours-long meltdown that was broadcast live on the internet, MTV personality Tila Tequila stripped off all her clothes and delivered a series of bizarre rants that left some wondering if she was experiencing a breakdown. But Tequila — who's attributed the episode to anxiety over a lawsuit she's filed against ex-boyfriend Shawn Merriman — is just the latest in a series of famous stars and broadcasters who've lost control in front of the camera. Here are some other notable meltdowns:1.
